I've been muddling through some of the source files for FreeBSD
5.2.1-RELEASE, and I've noticed that a large number of .c files
in /usr/src have something similar to below in them:
#ifndef lint
#if 0
static char sccsid[] = "@(#)cat.c 8.2 (Berkeley) 4/27/95";
#endif
#endif /* not lint */
#include <sys/cdefs.h>
__FBSDID("$FreeBSD: src/bin/cat/cat.c,v 1.29 2003/04/30 17:40:28
obrien Exp $");
1) Isn't 'if 0' always negative?
2) What is the __FBSDID line doing?
